Answer 1

Answer: a) x 1.04

               b) x 0.94 = 150.4

Step-by-step explanation:

a) find 4% of 160 = 6.4

    160 + 6.4 = 166.4

    166.4/160 = 1.04 therefore you multiply by 1.04

b) find 6% of 160 = 9.6

    160 - 9.6 = 150.4

    150.4/160 = 0.94 therefore you multiply by 0.94  which then equals to                      150.4

Answer 2

Answer:

To decrease 160 by 6% you have to do 160×.06 and you get 9.6. then you do 160-9.6 and you get 150.4
